Alkaloids from the root of Indonesian L.

Ari S Nugraha Rachada Haritakun Jacob M Lambert Carolyn T Dillon Paul A Keller

Nat Prod Res 2021 Feb 8;35(3):481-489. Epub 2019 Jul 8.

L. has been used traditionally in Indonesia to treat disease. Phytochemical studies on the alkaloid fractions from the root of L. from Malang-Indonesia resulted in the isolation of an unreported benzylisoquinoline alkaloid (+)-xylopine as well as four known alkaloids (-). The crude methanol extract and alkaloid fractions were tested against K1 and against bacteria (, , , , Methicillin-resistant ) with insignificant activities (MIC > 32 µg/mL). Individual alkaloids were tested against a human suspension cancer cell line (HL-60 leukemia cells) and two human fibroblastic cancer cell lines (A549 lung cancer cells and HepG2 liver cancer cells) in which compound as the most toxic alkaloid with IC values ranging from 20 to 80 µM.

Recovery of dopaminergic system after cocaine exposure and impact of a long-acting cocaine hydrolase.

Authors:
Jing Deng Ting Zhang Xirong Zheng Linyue Shang Chang-Guo Zhan Fang Zheng

Addict Biol 2022 Jul;27(4):e13179

Molecular Modeling and Biopharmaceutical Center, University of Kentucky, 789 South Limestone Street, Lexington, Kentucky, 40536, USA.

Dysregulation of dopamine transporters (DAT) within the dopaminergic system is an important biomarker of cocaine exposure. Depending on cocaine amount in-taken, one-time exposure in rats could lead to most (>95% of total) of DAT translocating to plasma membrane of the dopaminergic neurons compared to normal DAT distribution (~5.7% on the plasma membrane).

contains a number of unusual polyphenols, derivatives of resveratrol and naringenin, called spiro-flavostilbenoids, which have potent in vitro anti-inflammatory, antioxidant, and moderate cholinesterase inhibitory activities. To date, these compounds have not been tested in vivo for the treatment of neurodegenerative diseases. The aim of the present study was to evaluate the effects of both single spiro-flavostilbenoids (yuccaol B and gloriosaol A) and phenolic fractions derived from bark on scopolamine-induced anxiety and memory process deterioration using a model.
